The State of OpenTelemetry Profiling
Join us exploring OpenTelemetry profiling's evolution and future. We'll examine the changes in OTLP profiling protocol, highlighting how moving beyond pprof wire compatibility enables individual profiling events with timestamps and thread timeline visualizations.
Discover the practical implementation of profiling across the observability stack using the OTel Collector. Learn about its sophisticated capabilities in receiving, processing, and exporting profile data, along with data augmentation tools and community contribution opportunities.
Learn how off-CPU profiling complements traditional on-CPU profiling by revealing hidden unknowns. This comprehensive approach helps teams make informed decisions about system architecture and resources.
This collaborative presentation from the Profiling SIG showcases achievements and future directions in profiling, offering practical insights for comprehensive profiling solutions.
Continuous profiling with Open Telemetry
While most eBPF applications focus on network topics, eBPF also provides opportunities for profiling to improve performance and gain more insight into systems. This talk provides a short introduction into the eBPF based profiling agent, that got donated to Open Telemetry. It also describes how eBPF elements are used in the context of profiling and how it was and is possible to do stack unwinding for native and interpreted languages even on older Linux kernels and without support of modern eBPF helpers.
